entree sr STUFFING-BQE.

Application filed November T 0 all whom it may concern-1 Be it known that we, For Rooms and Minn Groves, citizens of the United States, residing at lllidian, in the county of Butler and State of Kansas, have invented certain new and useful improvements in a Stuffing- Box, of which the following is specifics. tion.

This invention relates to improvements in stuliing bones, more particularly to devices of this character employed 1. deep well operations for packing the polish rods of pumps thus used, and has for one of its objects to improve and-simplify tllerollstrud tion and increase the efficiency and utility of devices of this character.

Another objectof the invention is to pro vide a device of this character in which provision is madefor removing and inserting the polish rod without detaching the body of the stuiiing box.

Another object of the invention is to provide a device of this character in which provision is made for controlling pressure upon the packing gland, for instance to stop leakage, without removing any of the parts or stopping the motion of the polish rod.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and specifically pointed out in. the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Fig. 13 is a sectional view on a reduced scale, of the improved device.

The improved device comprises a hollow body or shell portion,conunonly called a .bell nipple, represented as a whole at 16, and reduced at the lower end, and threaded externally to enable it to be attached to a coupling 11, as shown in. 13, the latter uniting the main pump tube l2 and lateral discharge 13.

The shell 10 formed with an internal shoulder 14!: to support follower ring l5 and bearing upon the follower ring are a plurality of packing rings 16 of rubber or other suitable material.

The gland member of the device is repre sented as whole at 17 and tits closely within the shell 10 and bears its inner end upon the outermost packing ring 16.

At its upper end the gland 17 is enlarged attwo opposite sides as shown at 18 and the upper faces of the enlargement notched, as shown at 19. V l

A pressure applying lever forms a part of the invention and is formed with two side portions 2021 united into a single hook 2-2, at one end and with spaced hooks 23-2-l at the other ends.

The lever members diverge from the single terminal hook 22 to the spaced terminal hoolrs 23 and 2 and engage loosely by the spaced sides in the notches 19 of the gland, as shown.

A link formed of a body portion 25 having a triangular loop at one end to engage in the hooks 23 and 24.- and an eye, 27 to engage the lateral discharge branch 1.3, serves as an adjustable fulcrum to the lever 20-21.

Suspended by a loop or strap 28 from the single hook 22 is a receptacle 29 of suitable size to receive any convenient weight material such as earth, stones, scrap metal, or-

lilre.

A strap or link 30 is preferably located on the two part lever to prevent them from being displaced laterally and thus being disconnected from the notches 19.

By this simple arrangement the requisite pressure can be applied to the gland member 17 to compress the yieldable packing rings 16 against the polish rod, a portion of which is represented at 31, and produce the requisite liquid tight packing to the rod, while at the same time the pressure may be readily and quickly increased in event of leakage caused by the wear of the packing rings or from other causes, by shifting the link member 25 along the dischargemember forth in the specification, but itwill be un-' derstood that an medications within the scope of the claimed invention may be made in the construction Without departing from the principle of the invention or sac-V rificing. any of its advantages.

What we claim is: r

1. A devioeoi theclass described associated with a Well tube and its polish rod and discharge branch and comprising a tubular body adapted to be attached to the Well tube, a packing gland engaging in said tubular body and adapted to compress packing rings against the polish rod, said gland having upwardly openin g notches, a lever device including spaced side members bearing loosely in said notches, and adapted to support a Weight device at its longer end, and a link engaging the two part lever at the other end, and slidably engaging the discharge branch.

'2. A deviceoi the class described associated with a Well tube and its polish rod and discharge branch comprising a tubular body adapted to be attached to the Well tube, a

packing gland engaging in said tubular body and adaptedto compress packing rings against the polish rod, said gland having upwardly'opening notches, a lever device including spaced side members bearing loosely in said notches, united in a single hook at one end and With spaced hooks at the other ends, said single hook adapted to support a Weight device, and a link ,havv ing aloop at one end engaging the spaced hooks of the lever and slidably engaging the discharge branch by its other end.

In testimony whereof, We affix our signs nor, scones:

tures hereto.
